It varies by set and changes frequently. Argos, Very, John Lewis, and Smyths all compete on price. Brick Sleuth compares prices across major UK retailers so you can instantly find the cheapest option for any set.
How often are LEGO prices updated?
We update prices daily across all tracked retailers. Price changes are detected automatically, and our system flags new deals and price drops as soon as they appear.
Can I get alerts when LEGO prices drop?
